Leaks and seams

[zenairman]

I really know nothing. I have just a few leaks in the seams of my trailer, it's gutted to the exterior skins, sikaflex 221?...sikaflex construction?... 3m 5200? I'd like to get the stuff at Homedepot or Lowes, maybe Whitecap. I'm thinking the 3m. The Marine is fast cure, but does Homedepot even carry it? and if so will it work? Has anyone used the 3m stuff? I mean for seams and the like.

Not what you asked, but I used Vulkem 116 gray and got it at both Lowes and Home Depot.

Try at HD Seamermate.Talked with an A Streamer who apllied 6 years ago and no leaks.I just did the interior seams of my gutted coach.Apllied to a drip from a screw hole in the AC while wet and it ever stopped the leak.I plan to use Parbond for the side seams and Tempro for the top.Parbond and Tempro at VTS .You can also get Tempro at Fastenal.

That should have been even stopped the leak and P Bond and Tempro on exterior.Alcoa Gutter Seal at VTS is also good. Just make sure anything you use is 100% polyurethane and not silicone

Newbie question perhaps... I've read "don't use silicone" more than once on the forums, but just sort of filed it away in my head because until today I didn't have a trailer. I'll be needing to keep up with the good work the previous owner has been doing to repair and avoid leaks, so NOW I want to know "Why polyurethane and not silicone?"

(It's not that I don't believe, it's just that I always want to know why. It's an OCD thing, I guess.

Silicone when it cures remains pretty much in the shape it cured in. polyurathane sealants are flexible after cure, and can be sanded if need be. Many reasons...I am sure others will chime in.

Silicone will eventually eat aluminum.

If you do use Parbond (http://www.inlandrv.com/catalog/images/51600.JPG), your work may look very unprofessional without some kind of applicator.

You can make a Parbond applicator by going to your local ranch or farm supply (or a pet doc) and get yourself a vaccination syringe and needle for cattle (get the largest diameter needle you can find). Take the grinder to the needle taking the tip off.
